M0931K Assumed To Be A Compact PIR Motion Sensor For Human Body Induction Scenarios Such As Smart Home Appliances And Security Equipment

General Description:

The M0931K is assumed to be a compact PIR motion sensor designed for detecting the movement of human bodies and small warm - blooded animals. It operates based on the principle of passive infrared detection, which senses the difference between the infrared radiation emitted by the target and the background environment. The sensor integrates a pyroelectric detector and signal processing circuit, featuring low power consumption, small size, and high sensitivity. It is widely used in low - power electronic devices that require human body induction, such as automatic night lights, smart sockets, and mini security alarms. It outputs a digital signal when a moving target is detected, facilitating quick integration with microcontrollers and other control devices.

Core Features:

1. Ultra - low Power Consumption: Its ultra - low standby current makes it suitable for battery - powered devices, effectively extending the service life of the equipment without frequent battery replacement.
2. Stable Detection Performance: It can stably work within a wide voltage and temperature range, and has strong anti - interference ability against ambient light and weak infrared interference, reducing false alarms.
3. Easy Integration: The compact module design and simple digital output interface allow it to be quickly soldered and connected to PCB boards, which is convenient for secondary development and integration into various small electronic products.
4. Cost - effective: It adopts mature PIR technology, with reliable performance and low manufacturing costs, making it suitable for mass - produced consumer electronics.
